Every day I see a huge number of messages like in the subject, posted to syslog... a full example of a few lines from "logwatch" might help:address not available resolving './DNSKEY/IN': 2001:500:2::c#53: 24 Time(s)[...]address not available resolving './NS/IN': 2001:500:2::c#53: 25 Time(s)[...]address not available resolving 'E.ROOT-SERVERS.NET/AAAA/IN': 2001:500:1::53#53: 5 Time(s)[...]address not available resolving 'G.ROOT-SERVERS.NET/AAAA/IN': 2001:500:2::c#53: 1 Time(s)

What is causing this? And, what do I need to tweek to satisfy whatever is happening?The confusing part, to me, is that these errors are logged even when no one is using the system except for a cloud backup that runs 24/7
